Fixes and extra functionality for emulators/doscmd

A year or so ago I emailed these patches to the maintainer
	and didn't get any feedback. Just rediscovered them so
	figured I should submit them before they get lost...

	patch-bioscursor
	Fixes the BIOS cursor handling so that programs such as the
	DOS edit.com and qbasic.exe work correctly

	patch-desqview-timeslice
	Allows INT15 timeslicing so that programs which support it
	can avoid 100% CPU utilization

	patch-quitemode
	Adds a -Q option which suppresses all video IO. Also helps
	optimize the input behavior especially when polling for
	input.

	patch-fossil-support
	Adds a -F option which enables support for FOSSIL IO using stdio.
